Digital convergence correction device and display device

Image Number 12 for United States Patent #6567058.

A problem to be solved by the invention is to prevent a digital convergence correction device from lowering in precision of correction performed when a relation between screen raster and effective area of picture varies.A vertical display area detection signal that corresponds to a position in vertical direction of a picture display area on a screen is generated in accordance with a vertical deflecting current. An address counter for generating an address for reading out correction data is controlled in accordance with the signal.
